600 Mr. M. Khalil on a new 
whole bursa is broader than it is long. It is 0°3 mm. in 
length and 0°5 mm. in breadth. The ventral ray is bifid, 
and arises separately from the lateral ray. The three 
branches of the lateral ray diverge widely from each other. 
The dorso-lateral ray separates at a higher level than the 
other two rays. The externo-dorsal ray arises in common 
with the dorsal. It ends a little distance away from the 
edge of the bursa. The dorsal ray is 018 mm. in length. 
It divides near its termination. Lach of its two divisions 
has a tridigitate end like the serration of a saw (fig. 5). 
The genital cone has a blunt apex. it does not protrude 
freely into the cavity of the bursa. 
The two spicules are equal and similar in shape. They 
are very long and slender, being 1:9 mm. in length. They 
are curved in part of their course. Their termination is 
filiform, and apparently the two spicules are united at their 
tip. There is an accessory piece 0:04 mm. in length (fig. 6). 
The posterior end of the female was not secured entire. 
The tail is short, and the vulva lies in the posterior third of 
the body. The female is oviparous. The ova are 72 w long 
and 45 ~ broad. They are voided in the unicellular stage. 
Habitat. Submucous nodules in the small and _ large 
intestine of Felis nebulusa (leopard) from the Malay States.

The lumen of the intestine of the animal contained a 
large amount of mucus tinged with blood. The mucus 
surface of the large intestine especially was studded with 
hard nodules, about 1 em. in diameter, projecting into the 
lumen. Their surface was covered with a thick layer of 
mucus. On being scraped the surface of the nodule was 
found to be smooth, with one or more minute openings at 
its apex. These were visible on account of the red-colour 
of the contents oozing from them. The nodules did not pro- 
ject on the serous surface of the intestine to the same extent. 
On section the hard tumour was found to be traversed with 
a convoluted canal tinged red with blood. The adult para- 
sites lie along these tracts commonly two in each tumour. 
Microscopical examination of the contents of these canals 
revealed eggs and larve in different stages of development. 
Similar larvee were found in the lumen of the gut. The 
extravasated blood was in the process of disintegration. 
On examination of sections made from these tumours, the 
mucus membrane covering the tumour was found to be 
intact, but extremely atrophied, the tumour lying com- 
pletely in the submucus tissue. The muscular layers of the
